The latest on D7000 skin tones?

don't forget, same lens on both cameras. Also, I recommend using a gray reference card for latter use in NX PP. Setting the same Kelvin temperature won't be as precise because different lens/AA filter combos do produce different color casts. The camera's Auto-WB tries to compensate for that, but a gray reference card is the bullet-proof method to remove that cast.

I say this, because in some of my test shots, setting the same temperature for the D300 and D7K, for instance, with the same Picture Control and lens, does show a difference in color cast -- small, but perceptible. The gray card (or white reference) gets rid of the difference. I do have some color balance/cast test shots I haven't time to post for this topic, but may now to assist in this discussion.

Now, the very valid question is whether one wants to bother with the complications of a gray reference card for normal shooting. The answer is: if color accuracy matters, then the answer is a resounding "yes!" If you are shooting a wedding or event or portrait session with two different cameras and don't want to surprise your client with different colors from shot to shot, then the answer is an even louder "YES!"

I suspect most enthusiasts will eventually let this go, and opt for a more "color interpretive" approach, though.
